Nan and Dorothy both shouted at the same time. As for Bert, he was so
surprised at having caught a fish, and at seeing the cat slide off the
deck with it, that he could say nothing. It was almost the same with
Harry. He had jumped to his feet, however, and had run toward Snoop,
but too late.

Then, all of a sudden, Snap, with a loud bark, gave one spring, and
the next moment he had jumped right over the deck railing, under which
Snoop had slid. Right over it went Snap, and down into the lake. For
he knew that Snoop had fallen in, and, being the kind of a dog that
asks nothing better than to save something, or somebody, from the
water, Snap was right on hand.

Snap did not stop to listen. He had, indeed, taken Flossie's doll with
him. He had been holding it on his front paws as Snoop slid overboard,
and, as he gave a jump, Snap did not come down on all four legs. He
jumped while he was yet standing on his hind ones, and of course the
doll went over the rail with him.

"What has happened?" cried Mrs. Bobbsey, as she heard the screaming,
and the splashes in the water. "Have any of the children fallen in?"
For she had gone to another part of the deck, with Dinah, out of sight
of the twins for a moment. Now she came hurrying back, and a single
look showed her that the children were all safe.

"As nearly as I can figure out," said Mr. Bobbsey, "Bert caught a
fish, Snoop tried to get it and fell into the water, and now Snap has
gone in after Snoop."

"And Snap has my doll! She'll get all wet--she'll be drowned!" cried
Flossie.

"I'll get her for you," offered Harry. But just now they were all
anxious to see what Snap and Snoop did. Mr. and Mrs. Bobbsey and the
children looked over the side of the houseboat. They saw the black cat
swimming about in the lake, and Snap, who was a fine water-dog, was
paddling toward her.

"Hadn't you better stop the boat?" asked Mrs. Bobbsey, for the
Bluebird was slowly floating away from the dog and the cat.

"Oh, yes, and Flossie's doll," added Mr. Bobbsey. "I guess you'd
better get in the rowboat, Captain White. It will be easier to lift
them out from there."

"I'll do it, Mr. Bobbsey," the captain said, as he limped down stairs
again. By this time Snap had swum to where poor Snoop was paddling
about in the water. The dog gently took hold of the cat by the back of
the neck, where her loose fur would give a good hold. Then Snap,
holding Snoop's head well up out of the water, started back for the
houseboat.

"Good old Snap!" called Mr. Bobbsey. Snap wanted to bark and wag his
tail, as he always did when any one spoke pleasantly to him, but he
knew if he opened his mouth to bark now, he would have to drop Snoop.
And Snap had hard enough work swimming, without trying to wag his
tail. On he came toward the boat.

By this time Captain White had gotten into the small boat, which was
pulled after the Bluebird, by a rope, and he was rowing toward the
dog. Seeing that the smaller boat was nearer, Snap swam toward that,
instead of toward the larger one. He held Snoop carefully up out of
the water.

"That's a good dog, Snap!" called Captain White, as Snap came nearer.
"I'll take her now."

The engineer lifted poor, wet, dripping Snoop into his boat. She
crawled close up to Captain White, for she was much frightened. After
Snap had delivered the cat he had rescued, he turned back again.

"Where are you going?" asked Captain White. "Don't you want to get in
my boat, too, Snap?"

"Bow wow!" barked Snap. This time he could open his mouth, as he was
not carrying a cat.

And so he was. After taking Snoop safely to the boat, Snap had seen
Flossie's doll floating on the top of the water, and had swum toward
that, just as he would have gone toward a floating stick, had there
been one near.

Taking the doll in his mouth, as he had taken the cat, Snap swam back
toward the small boat, where Captain White waited for him, now and
then petting poor Snoop. Just as the dog had done with the cat, so he
did with the doll, giving her to the engineer of the Bluebird. Then,
seeing that his work was all done, Snap once more swam toward the big
boat, not trying to get into the small one.

"Good dog, Snap!" cried Mr. Bobbsey, as he leaned over to lift him in,
for there were no steps by which to climb up the side of the Bluebird.

This time Snap barked and wagged his tail, and then he gave himself a
big shake to get rid of the water. He sent a regular shower of spray
all about.

"Come, girls!" cried Mrs. Bobbsey with a laugh, "this is no place for
us. We haven't our bathing suits on!" and she, with Nan and Dorothy,
ran back out of the way of the scattering drops from Snap's shaggy
coat.

A little later Captain White rowed up with Snoop and Flossie's doll,
and the little girl at once said she was going to put a dry dress on
the doll, so she wouldn't "take cold."

"Well," said Mr. Bobbsey, when the excitement had died down. "That's
over, at any rate. All that over one little fish!"

"That's so--my fish started it all!" said Bert. "I wonder what became
of it?" and he looked at his empty hook, dangling from the line of his
pole.

"The fish dropped off," said Harry. "I saw it. But it was only a
little one. It wouldn't have been any good."

"Poor Snoop!" said Mrs. Bobbsey. "All your trouble for nothing! You
didn't get the fish."

"And I think we are ready to eat," said Mrs. Bobbsey. "This traveling
on the water has given me an appetite."

"I guess it has all of us," spoke Mr. Bobbsey with a laugh, as he
noticed the eager, hungry looks on the faces of the children.

"And give Snoop and Snap something good and hot, so they won't take
cold," suggested Nan. "Though I don't believe they will this weather,
it's so warm."

"I'm going to give my dollie hot chocolate," said Flossie, who, by
this time, had put a dry dress on her pet.

The meal was a merry one, though at first the children, especially
Flossie and Freddie, were too excited to eat. Then, too, it was so
strange eating on a boat that was moving through the water, for the
engine had been started again. Several times, during the meal, the two
smaller twins jumped up from the table to run to the windows and look
out over the lake. At last their mother said:

"Now, Flossie and Freddie, you must sit still and finish your dinner.
Otherwise you may be ill. You'll have plenty of time to see things
after you leave the table."

Snap was soon dry, from lying in the sun, and, a little later, Snoop
was as warm and fluffy as before she had fallen into the lake. She
picked out a warm spot on deck near Snap, for they had been the best
of friends since the first day they had met, when Snoop came back from
her long trip to Cuba, as I have told you in another book.

All the rest of that day the houseboat traveled over Lake Metoka. The
children sat on Heck, and watched other boats pass them. Some of them
were loaded with lumber for Mr. Bobbsey. Others were pleasure boats,
and those on board waved their hands to the Bobbsey twins and their
cousins.

"Are we going to travel all night?" asked Bert of his father, when
Dinah called that supper was ready.

"No, we are going to anchor soon. We will go a little nearer shore
first, though."

It was such a pleasant evening, that even the little twins were
allowed to stay up on deck past their usual bedtime, looking at the
twinkling stars, and the lights of other boats on the lake.

When Flossie and Freddie did get to bed, they did not go to sleep at
once. It was very strange to them, sleeping on a boat in the water.

Finally the two little people dozed off, and then the older folks went
to bed. In the middle of the night Freddie woke up. At first he could
not remember where he was, and he wondered at the queer rocking motion
of the boat, for a little wind was ruffling the lake.

Whether it was on account of the bait they used, or because the fish
were not plentiful, the boys did not know, but they did not get even
one bite. Anyhow, they had fun.

The Bluebird went slowly across the lake. The Bobbseys were in no
hurry, and they wanted to enjoy the pleasant weather. For three days
they sailed over the blue waters, and then Mr. Bobbsey told Captain
White to steer toward Lemby Creek.

"We'll go through the creek into Lake Romano," said the twins' father.
"That is a much larger lake. We'll spend most of our houseboat
vacation there. We will also visit the big waterfall."

"That will be lovely!" exclaimed Dorothy. Though she lived near the
sea, she also loved inland waters, such as rivers and lakes.

The houseboat moved so slowly, and was such a safe craft, that Bert
and Harry were allowed to steer at times, when Mr. Bobbsey or Captain
White stood near them in case of any danger. The two boy cousins had
taken turns steering, until the Bluebird was close to the place where
Lemby Creek emptied into Lake Metoka.

"You'd better let me take the steering wheel, now," said Mr. Bobbsey
to Bert. "There is a little current from the creek into the lake, and
we don't want to run ashore."

In a little while the houseboat was safely in the creek. This stream
of water was narrow, though it was deep enough to float the Bluebird
easily. The shores were so close, at times, that the tree branches
overhung the deck, and brushed the rails.

"There's that boy--Will Watson!" spoke Nan. "You know--the one who
liked our boat so," and she pointed to the strange lad who worked for
Mr. Hardee. The boy was walking along the shore of the creek, a fish
pole over his shoulder.

"Oh, let's ask him how to catch fish!" proposed Bert. "We haven't had
any luck at all!"
